通風系統可以實現屋內和屋外的通風了，屋里和屋外的空氣就可以得到很好的流通，可以幫助空氣進行一個很好的互換的階段。通風設備該如何設計安裝呢？
    The ventilation system can be ventilated in the house and outside the house, and the air in the room and outside can be well circulated, which can help the air carry on a very good interchangeability phase. How should the ventilation equipment be designed and installed?
    1．送、排風口的距離要適當
    The distance between the and the exhaust ports should be appropriate
    排風口與送風口少保持3米的距離以防氣流短路
    At least 3 meters away from the air outlet to prevent air flow short circuit.
    2．選用合適的風閥 choose the appropriate wind valve
    從原則上講，系統風壓平衡的誤差在10％－15％以內，可以不設調節閥，但實際上僅靠調風管尺寸來調風壓是很困難的，所以，要設風量調節閥進行調節。
    In principle, the system wind pressure balance error is within 10% - 15%, can not set the regulating valve, but in fact, it is very difficult to adjust the wind pressure only by the size of the wind regulating tube, so we should adjust the air volume regulating valve.
    風管分支處應設風量調節閥。在三通分支處可設三通調節閥，或在分支處設調節閥。
    In the branch of the wind pipe, the air volume regulating valve should be set. A three way regulating valve can be set at three branches, or a regulating valve is arranged at the branch.
    明顯不利的環路可以不設調節閥，以減少阻力損失。
    The obvious disadvantage of the loop can be no control valve to reduce resistance loss.
    在需防火閥處可用防火調節閥替代調節閥
    The fire control valve can be used instead of the regulating valve at the fire damper.
    送風口處的百葉風口宜用帶調節閥的送風口，要求不高的可采用雙層百葉風口，用調節風口角度調節風量。
    The blinds at the outlet of the air outlet should be provided with an air inlet with a regulating valve. A double louver outlet can be used if the requirements are not high, and the air volume can be adjusted by adjusting the air inlet angle.
    新風進口處宜裝設可嚴密開關的風閥，嚴寒地區應裝設保溫風閥，有自動控制時，應采用電動風閥。
    Hot air inlet valve should be installed at the inlet of fresh air, and the insulation air valve should be installed in the cold area. When the automatic control is applied, the electric air valve should be used.

    3．風管的布置 The arrangement of wind pipes
    要盡量減少局部阻力，即減少彎管、三通、變徑的數量
    To minimize local resistance, that is to reduce the number of elbow, three, and variable diameters.
    彎管的中心曲率半徑不要小于其風管直徑或邊長，一般可用1.25倍直徑或邊長
    The center curvature radius of the elbow should not be less than the diameter or length of the duct. It can generally be used 1.25 times the diameter or side length.
    為便于風管系統的調節，在干管分支點前后，應預留測壓孔。測壓孔距前面的局部管件的距離應大于5b(b為矩形風管的長邊或圓形風管的直徑)，距后面的局部管件的距離應不小于2b。通風機出口處氣流較穩定的管段上宜應預留測壓孔。
    In order to facilitate the regulation of the air duct system, the pressure hole should be reserved before and after the branch point of the trunk. The distance from the local tube to the front of the pressure measuring hole should be greater than 5B (B is the diameter of the long or circular duct of the rectangular duct), and the distance from the local pipe to the rear should not be less than 2B. The pressure hole should be reserved for the stable pipe section at the outlet of the fan.
    4．新風進口位置 new wind import position
    進風口宜設在室外空氣比較潔凈的地方，保證空氣質量
    The inlet should be located in a cleaner outdoor air to ensure air quality.
    宜設在北墻上，避免設在屋頂和西墻上，并宜設在建筑物的背陰處這樣可以使夏季吸入的室外空氣溫度低一些
    It should be located on the north wall to avoid being located on the roof and west wall, and should be located at the shady side of the building so that the outdoor air temperature in summer can be reduced.
    進風口底部距室外地面不宜小于兩米，當進風口布置在綠化地帶時，則不宜小于一米
    The distance between the bottom of the intake and the outdoor floor should not be less than two meters. When the air inlet is arranged in the greening zone, it should not be less than one meter.
    應盡量布置在排風口的上風側，且低于排風口，并盡量保持不小于10米的間距
    As far as possible, the upper side of the exhaust port should be placed below the outlet, and the spacing should be kept as low as 10 meters.
    5．新風口的要求 the requirements of the new tuyere
    宜采用固定百葉窗
    It is advisable to use a fixed shutter
    多雨地區宜采用防水百葉窗以防雨水進入
    Waterproof louvers should be used in rainy areas to prevent rain from entering.
    為防止鳥類進入，百葉窗內宜設金屬網
    In order to prevent birds from entering, it is advisable to set metal mesh in louvers.
    6．排風管的新做法 New practice of 6. row air duct
    類似酒店客房的排風系統設計可如下考慮：利用排氣扇將室內風排到走廊的吊頂內,在走廊設排風管排風,為有效利用余熱,排風機可設置于衛生間。
    The design of the ventilation system for similar hotel rooms can be considered as follows: using the exhaust fan to drain the indoor air into the ceiling of the corridor and exhaust the wind pipe in the corridor, in order to use the residual heat effectively, the exhaust fan can be set in the toilet.
